Backspace key confuses autocomplete when deleting

[Greedquest]

In an empty module enter

Sub test()

End Sub

End Sub

Then select the middle End Sub and delete with the backspace key. Instead of removing as expected, it creates a new instance. Possibly related to #4139.

Block completion is currently "working" without a parse tree, which makes it rather unstable and erratic; I'd recommend disabling the entire feature for now (via settings > autocompletion settings).

I'm getting close to being PR-ready with my autocomplete work in my fork - block completion will be temporarily removed, and self-closing pairs are being completely overhauled (and fully unit-tested).
